Calculation of diving depth de-saturation periods - uses portable minicomputer to display all data necessary for safe diving and re-submerging, and is worn on wrist
The minicomputer is contained in a sealed-housing (1) on which is an operating switch (2). Another contact (3) starts the computer programme. A further contact (4) triggers a modification to the running programme by calling on a given subprogramme. The housing (1) has two or three digit luminescent displays which give a series of indication including the immersion duration in minutes by the display (5) composed of three digits numbered 0-2 and immersion d epth in metres by display (6) composed of two digits numbered 9-10. The computer shows max. duration not be exceeded in minutes by a display (7) composed of three digits (3-5). It shows max. depth not to be exceed in metres by a display (8) composed of two digits (11-12) and the duration of the next stage in minutes by display (9) composed of three digits (6-9). It shoes the dept of next stage in metres by display (10) having two digits (13-14). A lamp (11) when illuminated indicates limits by which display (7, 8) are exceeded.
